Title: Coin accumulation quantity controller for automatic vending machine
Inventor: MATSUDA EIJI
IPC: G07F5/22
Filed: 1989-05-31
Abstract: PURPOSE:To eliminate trouble that an automatic vending machine without any managing person automatically pays out coins to a change paying-out port by automatically paying out the accumulated coins at a determined time and automatically guiding the paid-out coins to a money collector, which is provided in the internal part of the automatic vending machine, at such a time. CONSTITUTION:At the prescribed time, in a state that the number of the accumulated coins counted by a number of accumulated coins detector 22 is more than an accumulation starting number stored in a storage device 25, a controller 20 drives a coin paying-out device 23 and controls a switching device 24 so that the coins to be exhausted can be guided to a money collecting side. Accordingly, in a coin accumulator 21, the accumulated coins exceeding the accumulation starting number are guided to the money collecting side. The number of accumulated coins detector 22 subtracts the number of the exhausted coins from the number of the accumulated coins. However, when this number of the accumulated coins is made equal with the accumulation starting number, the controller 20 stops driving the coin paying-out device 23. Thus, safety management can be executed.

Abstract: PURPOSE:To melt an active metal to a high temp. of excellent castability with high purity by providing a specific heat resistance layer between the skull of the active metal and a crucible constituted of plural water cooling type bar-shaped copper segments at the time of melting the active metal in this crucible. CONSTITUTION:The many water cooling type bar-shaped segments 2 made of copper and a crucible 6 formed of refractories 7 between these segments to a cylindrical shape are used as the crucible and a high-frequency induction current is passed from a power source 9 to an induction coil 1 provided on the outer periphery thereof to melt the Ti in the crucible 1 by the induction current at the time of melting the active metal, such as Ti, by the high-frequency induction current. The current does not flow in the crucible itself as the water cooling bar-shaped copper segments 2 are insulated from each other by the refractories 7. The current flows effectively only in the Ti 4 and the Ti melts with good electric power efficiency. The heat resistance layer 11 consisting of chemically stable Y2O3 and others which have a high m.p. and high thermal conductivity and do not react with the Ti is interposed between the skull 12 as the solidified shell of the molten Ti and the crucible 6, by which the Ti is sufficiently heated to the high temp. with the high purity and the castability is improved.

Title: Electrostrictive vibrator driving apparatus for ink jet printer
Inventor: SATOU TSUTOMU
IPC: B41J2/055
Filed: 1978-11-11
Abstract: PURPOSE:To make it possible to independently set both positive and negative drive signals as desired by means of a voltage control circuit so arranged to perform charging and discharging of the electrostrictive vibrator driving circuit at a given timing for the ink suction, ink drop formation and ink jetting. CONSTITUTION:The output D of a monostable multivibrator 8 moves to D from H level as the set time tD is elapsed. At the turning point, the second flip flop 9 is set and the Q output F goes to H level. This turns a transistor Q4 on and the charge of an electrostrictive vibrator 1 thus far charged netatively is discharged through the transistor Q4. Upon the end of the discharge, a detector 6 detects to determine whether the potential of the electrostrictive vibrator driving circuit is zero at the neutral point. This resets the D flip flop and the output F moves to L level to turn the transistor Q4 off. In this manner, the electrostrictive vibrator 1 serves to ensure optimum suction, ink drop formation and jetting of the ink.

Title: Device for manufacturing spiral fin tube
Inventor: TSUNODA MINORU
IPC: B23K13/08
Filed: 1995-06-06
Abstract: PURPOSE: To prevent leakage or spark through spatter or metal powder by thermally spraying alumina, an insulating material, on two surfaces of a square electrode. CONSTITUTION: An electrically insulating film 7 is formed by thermally spraying alumina, an insulating material, on two surfaces, a surface oppositely facing the fin 6 immediately after being welded as shown in hatched part on the side face of a square electrode 3, and a surface behind one oppositely facing a flat electrode 4. Consequently, conductivity is eliminated from the square electrode 3 in the direction opposing the fin 6; hence, a high-frequency current does not flow between the electrode and the fin, in spite of the accumulation of a metal powder generated at the time of sliding of the electrode on a tube stock 1 or a spatter from a weld zone between the electrode 3 and the fin just after the welding; therefore, leakage or spark is completely prevented.
